Company News


As of March 16, 2009, the Doering Engineering St. Louis office has moved to a new location. The office was operating from inside The Doering Center on Lemay Ferry Road.  

The telephone number for the St. Louis office has remained the same. The telephone number is 314-487-6913. However the fax number has changed to 314-843-1718.  The move affects only the St. Louis, Missouri office and not the office in Troy, Illinois.

The new office is located off of Griffin Road, 1/4 of a mile south of Butler Hill Road and 1 1/2 miles west of Interstate 55.



As of May 1, 2006, the Doering Engineering Illinois office has moved to a new location. The office began operating from a location on Edwardsville Road, but due to recent growth, larger office space was needed.  The Illinois office further strengthens the firm's ability to serve its clients by providing a complement to our existing Missouri office which opened in 1989.  This also gives us the opportunity to offer the same quality service to our existing clients in Illinois and reach a greater number of new clients within the St. Louis region. 

The telephone and fax numbers for the Troy, Illinois office remain the same. The telephone number is 618-667-6610 and the fax number is 618-667-6653.  The move affects only the Troy, Illinois office and not the office in St. Louis, Missouri.

The office is located off of Bargraves Blvd., one tenth of a mile north of Edwardsville Road (Rte 162) and one mile east of Interstate 55/70.


Doering Engineering continually strives to improve in every aspect. To that end we have redesigned our web page to better serve our existing clients, along with giving additional information about who we are for new and prospective clients.  There are many additions to the site, and we hope you will take the time to learn more about what Doering Engineering has to offer.

New Surveying Equipment Purchased

In the fall of 2005, Doering Engineering improved its technology and purchased new survey equipment that will help make jobs easier and more accurate.  Doering Engineering’s survey crews now use higher level equipment and recent technological innovations from Topcon Positioning Systems, Inc. including one new Robotic Total Station, two new Total Stations, three new Data Collectors and all of the peripheral equipment necessary to run the new technology.  With the new equipment, survey results are gathered, analyzed, and processed faster and easier using the Autodesk Land Development Design software. As Doering Engineering has enjoyed steady growth over the years, our company has recognized the importance of diversifying our survey department to meet our clients’ needs.
